Answer 1

Answer:

implementation hiding allows the programmer to change the way in which a method works internally without affecting the programs that utilize  the method.

Explanation:

Implementation hiding is an example of encapsulation in OOP which enables a programmer or coder to hide method implementation from outside world and in this technique the program is also not affected by the method that it is using

Answer 2

Answer:

Implementation hiding.

Explanation:

A method is a group of one or more statements, defined in a class. The class holds the attributes and behaviours of objects in its class and implements the defined method from an interface.

To avoid the method statements from been seen, it is encapsulated, hidden internally but functional when called upon. This encapsulation process is called implementation hiding.
